A Negative spoked Lunar Craters

The image below shows a reverse view of the Moon which highlights the visibility of bright ray craters. As shown here, most large rayed craters of the visible side of the Moon are near the lunar equator, Langrenus, Copernicus and Kepler. The crater Tycho is a big exception, as well as others that are clustered around the north polar region. A negative view as it calls attention to the rays that have their source crater as yet uncertain. The Bessel beam that crosses the Mare Serenitatis is a famous example. It can come from Tycho, but no other ray of Tycho comes so far from their source. It may come from the coast of Menelaus Serenitatis, but why the hell would reach this go so far? Fainter rays crossing the Imbrium could also long rays of Tycho, but they are not radial to that crater and are usually parallel to each other rather than diverge. This view also shows the distribution of the rays of Tycho. It is well known that some of the rays of Tycho extend westward, but here we can also see that some rays follow to southeast, with two exceptions towards the pole. The image below, like many other imagnes Moon, raise good questions that encourages us to ever want to study more and more our only natural satellite, the Moon

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
